From 7785bba299a8dc8fe8390a0183dad3cafb3f1d80 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Wed, 15 Feb 2017 09:40:00 +0100 Subject: esp: Add a software GRO codepath This patch adds GRO ifrastructure and callbacks for ESP on ipv4 and ipv6. In case the GRO layer detects an ESP packet, the esp{4,6}_gro_receive() function does a xfrm state lookup and calls the xfrm input layer if it finds a matching state. The packet will be decapsulated and reinjected it into layer 2.
